Physical substance
The physical substance, defined precisely.
Industrial oxyhydrogen is a stoichiometric gaseous mixture of hydrogen (H₂) and oxygen (O₂) in a 2:1 molar ratio — the exact proportion liberated when an electric current splits a water molecule. It is colourless, odourless, and exists only as long as the generator is producing it.
In an industrial setting, this mixture is introduced — at low, rate-limited concentrations — into the combustion environment of a host thermal asset. It is not a stand-alone fuel. It is not a storage medium. It is a transient, on-demand modifier of an existing combustion process.
How it is produced
How it is generated: water, electricity, electrolysis.
The HydroHub™ generator applies a controlled electric current across an electrolyte solution. The current dissociates water molecules into their constituent gases — hydrogen at the cathode, oxygen at the anode — combined as an industrial oxyhydrogen stream at the manifold.
Production is rate-matched to the host plant's combustion demand and interlocked with its protective systems. When the plant is outside operating envelopes, generation stops. There is no storage vessel, no bulk inventory, and no reactive gas held on site.
How it integrates
How it integrates into a thermal asset.
The oxyhydrogen stream is metered into the combustion air path of the host boiler, furnace, or kiln. No pressure-part modification is required. The Distributed Control System of the host plant is not altered. The operating envelope of the asset is preserved.
Within the combustion zone, the oxyhydrogen modifies the radiative behaviour of the flame envelope. The effective emissivity of combustion gases shifts, increasing the proportion of thermal energy transferred radiatively to working-fluid surfaces — water-walls, superheater banks, and tubing.
Operational role
Its operational role — and what it is not.
The operational role of industrial oxyhydrogen is to improve the efficiency with which an existing thermal asset captures the heat already released by its primary fuel. Outcomes are expressed in operator-native units: net heat rate, fuel-intensity ratio, and steam-side thermal balance.
Industrial oxyhydrogen does not replace a primary fuel. It does not create energy. It does not run a plant on water. It is an engineered intervention layer that improves the thermodynamic capture of energy already being released inside the host asset.
